Research on the Financial Maturity of the Yangtze River Economic Belt

The Yangtze River Economic Belt is a key development project in China, and financial development is the core driving force for economic growth in the Yangtze River Economic Belt. At present, the financial development of the Yangtze River Economic Belt is not balanced, and there is an urgent need to quantify the differences in financial development. Drawing on the research of "maturity model" at home and abroad, from the two new perspectives of subjective and objective, the financial development difference is introduced into the maturity model as an organic whole, forming financial maturity and its indicator system, then taking the Yangtze River Economic Belt as the research object, the principal component analysis method is used to calculate the maturity. The results show that the financial development of the middle and lower reaches of the Yangtze River Economic Belt has obvious gradient differences both subjectively and objectively. The financial acceptance of the lower reaches of the Yangtze River and the total financial structure and structure are significantly higher than the middle and upper reaches, while financial efficiency is lower than the middle and upper reaches due to factors such as financial costs. Therefore, the financial development of the Yangtze River Economic Belt needs to improve the systematicness of finance, coordinate the growth of financial volume and structural adjustment, and improve the overall financial operation efficiency.
